の特性面に与える影響も大きい。これを防ぐために導線
のテンションを弱めにしてコイル巻線がなされる。In the figure, 1 is a semi-cylindrical coil bobbin, and 2'is a winding guide portion provided on the front end opening side (B) and the rear end opening side (C) of the coil bobbin 1, respectively. A plurality of them are provided along the periphery of the opening. 3.
3'is a partition wall 4 provided on the inner peripheral surface of the coil bobbin, respectively.
The winding groove formed by 4 '. Denoted at 5 is a notch of a partition wall provided in the vicinity of the axial center of the inner peripheral surface of the coil bobbin in order to easily change and correct the winding distribution of the deflection yoke. A horizontal deflection coil is divided and wound in a saddle shape on the coil bobbin thus configured, and a coil conductor is crossed across the cutout portion of the partition wall as needed to change the winding distribution and adjacent coil grooves are provided. FIG. 3 shows a state in which the winding is performed the required number of times. By the way, when twisted conductors such as litz wire have recently been used for the deflection coil conductor, there is a tendency to apply a strong tension to the conductor wire during the winding process, and the coil bobbin is easily deformed and deflected. The effect on the characteristic surface of the yoke is also large. In order to prevent this, the coil winding is performed by weakening the tension of the conductive wire.

ている。<Problems to be solved> However, if the winding tension on the coil bobbin is weakened, the deflection coil may be wound in the adjacent winding groove across the notch during handling during assembly work after winding. When an external force is applied to the wired coil conductor, the winding position is likely to be displaced, and the deflection yoke characteristics vary.

〈解決するための手段〉 コイルボビンに分割して巻線した偏向コイル導線で切欠

ものである。<Means for Solving the Problem> A deflection coil conductor wire divided and wound into coil bobbins is applied with a fixing agent for fixing the deflection coil conductor wire to the winding portion of the notch.

It is an agent. The deflection coil wire is divided and wound in a saddle shape on the coil bobbin 1 so as to have a predetermined winding distribution, and a part of the deflection coil wire is wound in the adjacent winding groove across the notch of the partition wall as required. After the winding, a butyral-based or phenol-based fixing agent 6 is applied to the outer circumference of the conductive wire wound near the notch 5 of the partition wall and dried to fix the deflection coil conductive wire. The displacement of the winding position of the conductor wire is prevented.
